PLEASE I NEED THIS ASAP The length of a rectangle is 1 less than twice the width, w. Which expression represents the area of the rectangle?
o 2w(w - 1)
O 2w(1 - w)
O w(2w - 1)
o w(1 - 2w)

22 dimes and 9 nickels

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
